vdpauinfo missing 444 and actual width/height of the video surface. Quadro M5000, Driver 375.39, CentOS 7

Hi,

I have an NVIDIA Quadro M5000 card installed in a workstation, and have all four DP ports hooked up to four 4K monitors (2x2 Mosaic). I Installed CentOS 7, Nvidia Driver 375.39, and xorg.conf configured properly. I have a huge 7680 x 4320 desktop now. Yum.

The issue is that if i use a media player like mpv to play a 6k movie (6240x2700) using vdpau driver, it gives me this error:

VO: [vdpau] 6240x2700 yuv420p
[vo/vdpau] Video too large for vdpau.
Could not initialize video chain.

When I run vdpauinfo, it gives me this:

display: :0   screen: 0

I’m wondering why the 444 and larger video surfaces are missing here? Not sure what i’m doing wrong here. M5000 supports these formats according to: http://http.download.nvidia.com/XFree86/Linux-x86/304.60/README/supportedchips.html and https://developer.nvidia.com/video-encode-decode-gpu-support-matrix

This is the output of: locate vdpau

Thanks for the help!

Maxwell GPUs only supports up to 4096 x 4096 resolution videos for H.264 hardware decoding. GM200/GM204 GPUs also do not support HEVC or VP9 hardware decoding.

6K is exceeding the hardware decoder’s limits.

Pascal GPUs were designed with 8192 x 8192 resolution HEVC Main10/Main12 & VP9 hardware decoding support.

http://us.download.nvidia.com/XFree86/Linux-x86_64/378.13/README/vdpausupport.html#vdpau-implementation-limits

"VDPAU Feature Set H

GPUs with VDPAU feature set H support all of the same VdpDecoderProfile values and other features as VDPAU feature set G. Feature set H adds:

VDP_DECODER_PROFILE_HEVC_MAIN:

    Complete acceleration.

    Minimum width or height: 128 luma samples (pixels).

    Maximum width or height: 8192 luma samples (pixels) wide by 8192 luma samples (pixels) tall.

    Maximum macroblocks: not applicable."

"VdpVideoSurface

The maximum supported resolution is 8192x8192 for GPUs with VDPAU feature set H, and 4096x4096 for all other GPUs.

VdpVideoMixer

The maximum supported resolution is 8192x8192 for GPUs with VDPAU feature set H, and 4096x4096 for all other GPUs."

Newer Quadro Pascal cards like the P6000, P5000 etc can decode up to 8K res videos.

Thanks for the info. Is there any other workstation cards that can support HEVC_MAIN_444? Sounds like P5000/P6000 can only handle HEVC_MAIN_10 and HEVC_MAIN_12.

My requirement is to use hardware accelerator for 6k movies with 444 chroma subsampling (codec is flexible). Any suggestion is appreciated.

No hardware supports 4:4:4 hardware decoding. Best available is Main12 4:2:0 on Pascal.
